Tom Grills Joins the Cell-Guardian Partner Program

Elyria, OH — Rahm Sensor Development, Inc., the developer of Cell-Guardian™, a zero-touch inmate monitoring system that provides continuous, real-time oversight in correctional facilities, is proud to announce the addition of Tom Grills as its newest sales partner serving Indiana, Kentucky, Ohio, Pennsylvania, Tennessee, and West Virginia.

“Tom Grills brings a wealth of law enforcement experience, integrity, and valued relationships to our sales team,” said Kevin O’Connor, Sales Director at Cell-Guardian. “Tom will help us deliver critical safety technology to correctional facilities in the central U.S. He also serves as a product subject matter expert who will help us evaluate and advance the development of Cell-Guardian.”

Cell-Guardian uses patented sensor fusion technology that combines radar, thermal imaging, and computer vision, along with artificial intelligence (AI), to continuously monitor and detect an inmate’s condition, movement, risk behaviors, and falls in real time without physical contact or wearable devices. The device sends instant alerts to corrections staff and provides time-stamped video documentation to support legal protection and operational accountability.

“After 28 years in law enforcement, including two terms as an Indiana sheriff, choosing to represent Cell-Guardian was an easy decision. This technology is advancing rapidly, and it is the perfect time to be part of its growth,” said Tom Grills. “My established relationships with state and local governments allow me to personally introduce and demonstrate how Cell-Guardian can strengthen safety and improve monitoring in their facilities. As a husband, father, and friend, I support law enforcement by seeking out resources that protect staff and save lives.”
